Book excerpt: This study offers a panoramic view of the creative, expository, interpretive, dialectic, polemical, didactic and devotional phases of Dvaita philosophy, and its literature with a clear chronological setting of literary, historical and epigraphic materials. Written in lucid style it presents a vigorous and sparkling historical exposition of the mighty currents of Realistic Theism, originating in the Vedic and post-Vedic sources of Madhva philosophy finding their culmination in the Dvaita Vedanta of Madhvacarya, and the long line of his great commentators and followers, over a period of seven centuries from the thirteenth century onwards.
